My understanding of some neuro-psychological features of humanity, lead me to believe that mankind is currently deprived of activities like touch, including maternal and non sexual touch, orgasm, trust relationships and general affection. Based on what I know of the mind, and am theorising, I believe that this behaviour would improved mood, peacefulness, sociability, trust between people and general psychological profile.
I have heard academics also suggest that modern aggression, and violence is connected directly to sexual taboo, and a lack of non-sexual touch. Basic sensory deprivation has been shown to increase violence in some.
Here John Prescot argues:
"I believe that the deprivation of body touch, contact, and movement are the basic causes of a number of emotional disturbances which include depressive and autistic behaviors, hyperactivity, sexual aberration, drug abuse, violence, and aggression."
"Human societies differ greatly in their treatment of infants. In some cultures, parents lavish physical affection on infants, while in others the parents physically punish their infants. A study of anthropological data by the author  found that those societies which give their infants the greatest amount of physical affection have less theft and violence among adults, thus supporting the theory that deprivation of bodily pleasure during infancy is significantly linked to a high rate of crime and violence."
Social monogamy appears to be pretty uncommon in modern hunter gatherer societies. Theres some genetic evidence that monogamy started around the same time as agriculture.
Certainly touch taboo, as in non-sexual touch, that we have in modern society, seems extremely unlikely, especially given that most early societies, even post agricultural ones celebrated sex as sacred.
For example, the egyptians used to have public sexual enactments, as part of their religon. This evidence for sacred regard of sex goes pretty far back.
So unlike today, there would have been no cultural impetus not to touch, for fear of it being regarded as sexual, as thus taboo.
If a grok hugged another fellow grok, its doubtful he would have avoided genital to genital contact, for fear of it being considered a come on, like modern huggers do.
Moreover, most probably, if a mother, parent, or elder hugged a child, there would have been no modernised fear of pedophilia, or other social judgements, because of this lack of taboo.
Basically did stone age people touch, have sex more, and were they polygymous?
And what is the neurochemical, psychological, and physiological implications of not living that way?
Does anyone have any interesting studies?
(Or just thoughts on these ideas)
Its somewhat academic, because the society we live in, is the society we live in, but at the same time, its something id like to give some thought. Social dynamics are a reasonably big part of being a human being, and those social dynamics are not guided by how we live now, but how we have evolved.
